Threadlockers & Retaining Compounds

Threadlockers and retaining compounds help secure suitable mechanical assemblies where vibration, clearance, movement or service conditions require an engineered adhesive solution. This range is for correctly prepared threaded fasteners and compatible cylindrical fits—not for repairing damaged threads, worn bores or incorrectly selected hardware.

Select the compound by joint function

Threadlockers are formulated for suitable threaded assemblies to help resist vibration loosening. Retaining compounds are designed for compatible cylindrical components such as bearings, bushes, sleeves or shafts. Before choosing, confirm fastener size, joint clearance, material, operating temperature, exposure to fluids, required strength and whether future disassembly is expected.

Preparation, assembly and cure time matter

Clean mating surfaces in line with the compound instructions, apply the stated amount, assemble within the working time and allow the full cure before returning equipment to load or service. Oil, moisture, contamination, poor fit and incorrect temperature can reduce performance. Use Parts Cleaners & Degreasers only where the cleaner and compound instructions support that preparation process.

Threadlockers & Retaining Compounds FAQs

Does threadlocker replace the specified torque?

No. Tighten the fastener using the required method and torque. Threadlocker supports a correctly assembled joint; it does not correct damaged threads, an incorrect fastener or an unsuitable clamping arrangement.

Can retaining compound repair a loose bearing housing?

Only use a retaining compound within its stated gap and application limits. A worn, damaged or structurally compromised housing must be assessed and repaired or replaced as required.

How long should I wait before using the equipment?

Follow the individual product’s cure-time guidance, noting that temperature, material and joint condition can affect cure. Do not assume handling strength is the same as full service cure.
